ELECTRICAL-LAMP FIXTURE Specification of Letters Patent.

Patented Feb. 16, 1909.

vide a fixture of this character such that it can be economically manufactured, and easily connected up and readily repaired.

In the accompanying drawing Figure 1 is a vertical section of one form of my improved fixture: Fig. 2 is an inverted lan View of the same, withoutany lamp in p ace, and with the cover partly broken away; and Fig, 3 is a sectional view of a part, to show the line conductor connections;

In this drawing I have shown my inven tion as embodied in a fixture employing the screw lamp sockets of the Edison type,but I do not wish to restrict myself thereto.

One of the features of my invention is the mounting of the lamp-carryin their contacts directly upon t e insulating base. In the construction shown in Figs. 1, 2 and 3, the baseA of porcelain or other suitable insulating material has contracted central portions and ledges 16 and 17, somewhat after the manner of the. base of my patent of March 22, 1898, No. 601,108, but in this instance the lower central portion a is shown as a separately molded piece. The two parts may be held together by a nut f on the central bolt F. Each lamp socket is composed of a metallic shell or ring terminal B and a spring contact finger C. The shell B in the Edison type is threaded to receive and hold the screw ringterminal of the incandescent lamp, while the finger C is adapted to make contact with the central end terminal of the lamp. Each shell B is formed or provided with two tongues or flanges b and b, by which the shell may be secured directly to the insulating base by the screws 5 and 6. The line conductor for connection with the shells may be brought in through an opening 7, Fig. 3, and con nected to an L-shaped terminal plate 8, which may be in contact with the tongue. 11 of one of the socket shells and secured by sockets and the same screw 6, which secures that ton e of the socket to the base. The several soc et 2, may be electrically connected up in any suitable way, as b means of a bare wire 10 positioned on the edge 17 in the face of the central portion a of the base, and makin shells. Each shell has an insulating ring or bushing R screwed onto or otherwise secured to its outside to protect-it from contact with the metallic cover E which is detachable and held in place by a screw nut on the threaded end of the central bolt. F. This cover hasopenin s 6 formed in it for the insertion of the amp bases into the sockets and for the artial protrusion of the lower edges of the ushings R to hold the cover E n place rotarily, without interfering with the free removal of the cover when the nut is detached.

The centre end contact or terminal C of the socket is preferably formed of a bent plate secured to the insulating base by a screw 11, inserted from the back, I prefer to provide one of these plates 0 with a curved wing 12, Fig. 3, having a binding screw 13 for securing the end of the line conductor which may be brought in through a hole 14 in the base, Fig. 'The several contact plates C may be'connected up in any suitable way, as by a bare wire 15.

. claim as my invention z- 1. The combination with a suitable base or supporting part, of a ceivers and associate contacts mounted upon said base, an insulating bushing or ring surrounding each of said receivers, and a detachable metallic casing having a lamp opening opposite each of said receivers, the bushings and casin being arranged to permit the removal 0 the casing without (listurbing or removingthe bushings.

2. The combination with a suitable base or supporting part, of a plurality of threaded lamp receiving shells and associated center contacts carried thereby, a threaded insulatin bushing 11 on the exterior of each of sai threaded s ells, and a detachable metallic casing havin an openin op osite' each of said threade shells, sai bus ings and casing being arranged to permit the removal of the casing without disturbing or removing said bushings.
